Welcome.napp

: The dreamer's operating system.

Which was the last time you saw an OS with a soul, a vision, an ambition — that actually feels human. Not a committee decision. Not another reskin of something you've already tried. NebiOS is what happens when someone gets tired of waiting for something genuinely different, and decides to build it themselves. — Built by Sarp M. under NebiSoft.

What is NebiOS?

NebiOS is an OS and a platform built on Ubuntu LTS. The goal: take what Linux never got right, add what nobody tried, and build it with a clear vision. NebiDE, the NebiOS Application Runtime, and a growing ecosystem — NebiCloud, Bundle Store — are all part of that.

It started as a hobbyist SUSE Studio experiment called Spez Linux, became Ubuntu-based in 2018, and by early 2020 the real vision had taken shape — privately, under the name Nebisa Independent Project. One person. One idea: a unique, adaptive UI that works seamlessly across every type of device, backed by a real ecosystem.

Experience the most unique desktop

NebiDE is the desktop environment behind NebiOS's adaptive, opinionated UI. Development started in late 2021 with NebiOS 2.0 Ant. In November 2023, the full Wayland-only rewrite began — marking the start of NebiOS X's development.

Opinionated where it matters: two panels, limited layout customization — by design, not by laziness. But where it counts, the power is yours: your background can be a photo, a video, or even that YouTube link someone sent you (yes, it works). Widget-first philosophy means your desktop is alive, not static. Choose your blur algorithm — Kawase, Gaussian, Bokeh. And so on.

Built on Wayfire. Most Python components compiled with Nuitka.

Apps that are both safe and fast.

NebiOS Application Bundles (.napp) rethink how apps should work on Linux. Portability of AppImage, speed of native packages, security of Flatpak — in a balanced way that minimizes the trade-offs of each. A granular permission system that stays out of your way, no heavy middleware required. Each app installs per user, stays contained, and just works.

.napp is exclusive to NebiOS — part of what makes the ecosystem its own. Bundle Store is where you find them. Parallel downloads, third-party repository support, and a recommendation algorithm that prioritizes quality over popularity (WIP) — and it's growing.

Design that has a name.

Flat-Skeuomorphism is NebiOS's visual identity — introduced in NebiOS 3 "Galata" in 2023 and carried forward as a deliberate choice, not a trend. It sits between two worlds: the clarity of flat design and the tactility of skeuomorphism. Shine, depth, shadow, and a careful balance that makes every element feel crafted rather than generated.

Most modern interfaces converged on the same gray rectangles and called it "clean." Flat-Skeuomorphism disagrees. Objects have weight. Icons have character. The desktop feels like home — not just a productivity surface you tolerate.

This isn't nostalgia. It's a design language built for the present — before Depth Gel made depth fashionable again.

One account. Everything connected.

NebiSoft services are a growing ecosystem built around NebiOS — Location Services, NebiCloud, and more to come. Most are powered by open-source technologies like the latest versions of Nextcloud.

NebiCloud gives you 10 GB free storage to start: a built-in password manager, cloud music and podcast streaming, contacts, tasks, calendar, and device location tracking (WIP for NebiOS integration). EU-based servers, zero telemetry. Your data stays yours.

You don't need an online account to use NebiOS at all. The ecosystem is there when you want it, invisible when you don't.

More than software. A culture.

NebiOS is built with the belief that a desktop should feel alive — not just functional. That's why, alongside the design and the engineering, there's the NebiSoft Artist Support Program.

It started with NebiOS X's public beta: Loading Artist comics, readable right from the desktop widget. Since then it's grown — stickers, new sources, new artists like Safely Endangered and xkcd. Not as a revenue play. Not as marketing. Just because a desktop that includes real art, made by real people, is a better place to spend your time.

More partnerships are coming. The goal stays the same: make the desktop more human.

Ready for what Linux isn't.

NebiOS X was among the first Ubuntu LTS-based distributions to go Wayland-only — no native X11 session, XWayland for legacy app compatibility. The convergence vision — one OS, seamless across PC, mobile, and tablet — is being built version by version.

Most new distributions innovate only on the backend. NebiOS takes a balanced approach: the daily user experience (NebiDE, flat-skeuomorphism, widget system) and the foundation (napp-runtime, hwstatusd, and more) evolve together. Neither side is an afterthought.
